Are these the same Gentry Eagle boats?
 

I think the red one is 46 ft and the white is 50ft, are they the same boat modified?

I think that they are the same boat and I also believe that the dimensions have remained the same.
Unbelievable as you have found two practically identical photos to 8 years of distance and that they allow us to appraise well the similes between them.

Yes they are they same hull.

What about these two...
 

I know they are the same boat, but what boat was it before Tom got it? Looks to be about a 38ft cougar...don't think its wood but could be...

38ft GENTRY CAT

It was ex-Peter Stuyvesant,ex-Limit Up.

Check out thread re Limit Up in Historic Section.

I think that it was simply a new boat and Gentry it was the first one to drive it in a competition.
The same year to the Viareggio worlds Gentry brought another new cat in aluminum of Cougar of 40' (I believe) always with the central cockpit and the places (two) beside.

Gentry Boat 1991
 

A little snippet from the past complete with wing.

That boat has been talked about in past threads with umpteen length references and various construction materials,but now finally it`s looks like settling down to be alloy 48ft stretched to 50ft.Ex-Budweiser.

The 38ft red/white Gentry is wood construction and this has been confirmed in past threads from them that should know, that it is an ex-toleman boat,and that when it sunk in 1990,it was referred to as a 10yr old boat i.e.Limit Up (1980) as raced by Mike Doxford.

50' with the wing.
For the war of the lengths Crouse on Searace in 1984 speaks of 46.'
In an aerial photo of the 1984 Key West docks the cat of Gentry is beside the Popeyes of Copeland and they seems twin in length.

If memory serves me correctly I believe it was a 41 and he ran it somewhere out of country one time at some point in time I remember see it at Gentry's shop with Michelobe graphics on it!!!!

It was a 46 but with the addition of the bussel to facilitate the wing it became 50
